COSO JUNCTION, Calif. (AP) - A swarm of small earthquakes has struck a remote Central California area but there are no reports of damage or injuries.
The U.S. Geological Survey says the largest in the series - a magnitude 4.3 - hit at about 5:39 a.m. Monday. At least half a dozen smaller quakes followed in the mountain and desert region about 150 miles north of Los Angeles.
The quakes were centered 9 miles northwest of Coso Junction, an unincorporated community along U.S. 395 in Inyo County between the Sequoia and Death Valley national parks.
USGS geophysicist Julie Dutton says earthquake swarms are not uncommon and can happen when stress is slowly released in a region.
